2. Empty the Trash

To be honest, this is more a reminder than a method. Everyone knows that we can directly drag files to Trash when we want to delete something on Mac. But you may not have the habit to click “Empty Trash” afterward. Remember that the deleted files will not be completely removed until you empty the Trash.

To do this, just right-click Trash, and then select Empty Trash. Some of you may surprisingly have got some free Mac storage.

How to Set up Empty Trash Automatically

4. Uninstall the Unneeded Apps

Many people usually download hundreds of apps on the Mac but hardly use most of them. If you are one of those people, it’s time to go through the applications you have and uninstall the unneeded ones. It can sometimes save up a lot of space because some of the apps can occupy a big chunk of storage even if you don’t use it.

To delete an application, there are also different ways:

  • Use Finder: Go to Finder > Applications, identify the apps you no longer need and drag them to Trash. Empty the Trash to uninstall them.

  • Use Launchpad: Open Launchpad, long press the icon of the app you want to remove, and then click “X” to uninstall it. (This way is only available for apps downloaded from App Store)

5. Delete iOS Files and Apple Device Backups

When your iOS devices are connected to your Mac, they may backup without your notice, or sometimes you just forget and have backed them up for multiple times. It’s possible that iOS files and apple device backups take up a lot of space on your Mac. To check and delete them, just follow the ways:

Again, if you are using masOS Sierra and later, click the “Manage” button at where you check the Mac storage, and then choose “iOS Files” in the sidebar. The files will show in last accessed date and size, and you can identify and delete the old ones that you no longer need.

Actually, the access to the Caches folder is similar to that of the Backup Folder. This time, open Finder > Go > Go to Folder, enter “~/Library/Caches”, and you will be able to find it out. The caches are usually divided in different folders in the name of different apps and services. You can sort them by size and then delete.

Part 3: After freeing up disk space: How to maintain a good state of disk

Here are some tips that you can follow to keep your disk with stable free space:

1. Organize and clean regularly: At least once a month, delete any unnecessary files or programs that are no longer needed. Use a disk cleanup utility or Macube Cleaner to remove temporary files, caches, and other clutter.

2. Manage software and updates: Check for updates regularly to ensure optimal performance and security. Keep your operating system and all installed software up to date with the latest patches and updates.

3. Avoid disk overload: Be aware of the amount of data stored on the disk. Avoid filling it to its maximum capacity as this may cause performance degradation on your Mac. Aim to keep at least 15-20% of free disk space for smooth operation.

4. Back up data regularly: Create backups of important files regularly. This step ensures that even if disk problems or failures occur, your data remains safe and recoverable. But if you have lost your data, we recommend using Eassiy Data Recovery to help you recover your data efficiently.

5. Control startup programs: Reduce the number of programs started at startup. Starting programs unnecessarily can significantly slow down the system's startup process and waste disk resources.

Keep in mind that these practices may vary depending on your operating system. Check out the Ultimate Guide to Check, Analyze and Clean Up Disk Space on Mac (Step by Step) for best practices in maintaining disk health.

Part 4: FAQs:

Q1: Why does my Mac have 50 GB of Other on storage?

Other Storage includes various types of files like plugins, caches, documents, and system folders that don't fit into specific categories like applications, photos, or videos. These files don't harm your Mac but can take up space.

Q2:How do I delete files from my computer but not iCloud?

Open the iCloud app on your computer and go to the "Options" menu next to iCloud Drive. Uncheck the box next to iCloud Drive to disable it. This will prevent new files from syncing to iCloud but will not remove any files that are already stored in iCloud.


That’s what you should know and the things you can do when you want to clear your disk space on Mac. There are definitely a number of ways to manage Mac storage, like emptying the Trash, using Apple built-in tools, uninstalling apps, deleting iOS backups, removing caches, clearing junk mails and browsing data.
